论文摘要
我们研究了与共振的种间混合物中的三体碰撞$ p $ - 波 - 波相互作用。我们三体有效相互作用强度和衰减率的结果对于理解这些稀释量子流体的稳定性和寿命至关重要。关于共鸣，我们发现，无论短期相互作用的细节如何，都会出现一类通用散射途径。这普遍产生了一个显着的制度，在这种情况下，三体有效相互作用在非弹性衰减和两体有效相互作用上占主导地位。此外，我们发现一系列依赖质量比率的三聚体共振。
We study three-body collisions within ultracold mixtures with resonant interspecies $p$-wave interactions. Our results for the three-body effective interaction strength and decay rate are crucial towards understanding the stability and lifetime of these dilute quantum fluids. On resonance, we find that a class of universal scattering pathways emerges, regardless of the details of the short-range interactions. This gives rise quite generally to a remarkable regime where three-body effective interactions dominate over both inelastic decay and two-body effective interactions. Additionally, we find a series of mass-ratio-dependent trimer resonances further from resonance.
